(Cl.105-133) This invention relates to rail motor cars, and has for itsprincipal object to relieve the framework of the car body from the mainload of the power plant and place it (and, therefore, the

center of gravity of the whole) nearer to. the ground, but above thesupporting springs in fixed relation to the car body in operation.

This is accomplished in the present embodiment by providing the bodybolster with a special framework (for convenience, called a motor bed)which supports the motor directly and also forms a means of connectionbetween the body bolster and the frame of the car body that transmitsand distributes the stresses to advantage and makes the 1 truck andmotor removable from the car as a subassembly for inspection, repair andreplacement.

Fig. 10 is a sectional view taken on the line Ill-l0 of Fig. 9 withparts broken away.

The car body 10 is mounted on a leading or motor truck, generallyindicated by I l and an articulating truck, generally indicated by 12.The

a motor 13 and generator I4 are carried by a motor bed l5 forming aframework or extension of the body bolster 16 of the truck ll.

The motor bed 15 is a generally rectangular frame (see Fig. 9) inclinedat its sides and ends to correspond with the flaring walls 11 (Figs. 1and 2) surrounding an opening in the frame of the car body which permitsthe motor to be entered to the position shown in Fig. 1, or withdrawn tothe position shown in Fig. 2. v

The truck, generally indicated by H in Figs. 1 and 2, includesconventional wheels 18 (Fig. 3)

fixed on axles supporting journal boxes, which carry the ends of theequalizer bars 19 equipped with seats for the springs 20, bearing thetruck frame it. Hangers 22 hinged to the truck transom 23 support thefree ends of cantilever springs 24, fixed in the housings 25 of thetruck bolster 26, having a center bearing 21 and side 5 bearings 28 forthe body bolster 29.

The body bolster is a steel casting, in the main composed of spaced webs30 (Figs. 5 and 6), extending between top and bottom flanges3l and 32.At the center, the bolster is fitted to a body 10 center plate 33cooperating with the truck center plate 21 and receiving a king pin 34passing through the tubular boss 35 (Fig. 5).

The motor bed comprises a fabricated structure, made up chiefly of theextruded aluminum sec- 5 tions. At each side (Figs. 4, "I, 8 and 9)there is a longitudinal bar 36 laid crosswise to the body bolster 29 andextending between and riveted to end castings 31 and 38. Just inside ofeach bar 36 is a bar 39, somewhat arch shaped in cross sec- 20 tion,riveted at 40 to the top flange3l of the body bolster 29, riveted at 4|to the bar v36 and riveted at 42 to the end castings 31 and 38. Each bar39 is surmounted by a sort of rail 43, riveted in place at 44. 25

The inner side of each member 33 is supported lengthwise by a sort ofangle 45 riveted to it at 46, and to the body bolster at 41. Each of thejoints between the several extruded sections of aluminum is reenforcedby a tongue and groove, 30 indicated at 43 in the general line of therivets.

The inner flanges of the bars 33 are reeni'orced byZ-bars 49- (Figs. 4and 5) which rest on steps 50, carried by the end,castings 31 and 38,and steps 5| carried by the body bolster, and are 35 riveted top andbottom.

A sheet of metal 52 extending beneath the zbars 49 and between the bodybolster and each of the end castings 31 and 38 serves to close thebottom ofthe motor bed.

The motor bed in this instance is built to bear a Diesel motor drivingthe generator l4, and it is arranged on the body bolster to place thecenter of mass approximately .over the king pin 34.

The car frame includes a center sill 53 (Fig. 9) 45 the front end ofwhich is fixed to the center of a cross sill 54 extending between theside sills 55 just to the rear of the opening 55 for the motor or powerplant. At the front of this opening them is a cross sill 51, alsoextending between the 50 side sills 55, and the two cross sills areconnected by longitudinal stringers 58.

A partial elevation of the sill 54 is shown in Fig. '7, where it will beseen that the stringer 58 rests on and is secured to a stepped seat 53,by 55 A partial elevation of the cross sill I1 is shown.

in Fig. 8, where it will be seen that the depth is reduced where thestringers ii are fitted over and riveted to offset portions of the topand bottom flanges 63 and 84 (Fig. 10) beyond which the end portion 85is given a peculiar shape to fit the side sill I and the channeled floorstringer 62 Turning to Figs. 4 and 5, which are transverse andlongitudinal sections, respectively, it will be seen that the outer sidewalls of the motor base slope upwardly and inwardly and that thecorresponding inside walls of the car frame. surrounding the opening 56are inclined in the same way. Thus, the frame of the car telescopes overand fits tightly on the motor base, as shown in Fig. 3.

From Figs. 3 and 4 it will be seen that the extreme ends 81 of the bodybolster 29 extend beyond the stringers 58, and are bolted to castbrackets 66 of peculiar shape, which connect the stringers 58 with theinside sills 55 and the floor stringer 82.

This scheme of construction makes a strong connection between the bodybolster and the body that distributes the stresses due to driving,braking and side thrust, and it makes the power plant for the most partindependent of the body so far as support is concerned, but fixed withrespect to the body for control.

The car body is made fast to the motor bed and body bolster by bolts 88.Removing these and disconnecting the controls, the water hose 69 (Fig.3) etc., leaves the car body free to be raised, as shown in Fig. 2, whenthe motor and truck can be readily removed and replaced.

The particular form of the invention here shown was built as part of athree-section articulated car for fast rail service. The body bolsterl6, the cross sills 54 and 5'! and the brackets 06 are of steel, but theremainder of the framework is aluminum.

The peculiar shape is to reduce air resistance in furtherance of whichmetal masks 10 secured to the truck frames approximate conformity withthe body lines. a

The sides of the engine bed, made up as they are in box-like fashion,not only serve as girders in supporting the engine load, but inaddition, they serve to transmit the energy of engine inertia to thenose structure in the event of collision, and thus assist in clearingthe track of obstacles.
